Hello @financegeek
Thank you for reaching out on the community and telling us about your issue. I believe what you'd be looking for is an asset account in this case. You can find it in the top left clicking the + on the blue bar. In the list you'll be able to see asset towards the bottom half. You'll also have a register to track the income on the house as well as any expenses.
Please let us know if this helps resolve the issue for you.
Thanks,
Quicken Francisco
